一、源码
index.html:
<!DOCTYPE html>

<head>
<meta charset="UTF-8"/>
<title>购物车小案例</title>
<link rel="stylesheet" type="text/css" href="./css/style.css"/>

<body>
<div id="app">
<div v-if="books.length">
<table>
<thead>
<tr>

<tbody>
<tr v-for="(item,index) in books">

<h2>总价格:{{totalPrice | showPrice}}</h2>

main.js:
const app = new Vue({
el: '#app',

},
methods:{
/* getFinalPrice(price){
return '¥' + price.toFixed(2)
} */
increment(index){
this.books[index].count++
},
decrement(index){
this.books[index].count--
},
removeHandle(index){
this.books.splice(index,1)
}
},
filters:{
showPrice(price){
return '¥' + price.toFixed(2)

},
computed:{

totalPrice = 0
for(let i = 0;i < this.books.length;i++){
totalPrice += this.books[i].price * this.books[i].count

return totalPrice
}
}
})
style.css(css样式)
table{
border: 1px solid #e9e9e9;
border-collapse: collapse;
border-spacing: 0;
}
th,td{
padding: 8px 16px;
border: 1px solid #E9E9E9;
text-align: left;
}
th{
background-color: #f7f7f7;
color: #5c6b77;
font-weight: 600;
}
二、简单叙述
style.css修改样式;
index.html为主要界面,在其中调用vue.js和main.js;
